Air quality in Gujangbagh right now
Right now the modelled US Air Quality Index for Gujangbagh, Xinjiang, China is 174, which falls in the "Unhealthy" band (up to 200). Everyone should reduce prolonged or heavy exertion outdoors; sensitive groups should avoid it and keep windows closed.
The index is driven mainly by PM2.5, whose own sub-index is 174. Fine and coarse particles come from traffic, heating, industry, dust and smoke; they build up on calm nights and clear when wind or rain arrives.
PM2.5 is 101 µg/m³, 6.7 times the WHO 24-hour guideline of 15 µg/m³; PM10 is 231 µg/m³ against a guideline of 45; ozone is 27 µg/m³ (below the WHO 8-hour level of 100); nitrogen dioxide is 14 µg/m³ (below the 24-hour guideline of 25).
Also this hour: desert dust at 261 µg/m³, high enough to haze the sky, carbon monoxide 802 µg/m³.

For context, the median across 3,909 cities worldwide is 57.
Model vs measured
We found no measured PM2.5 sensor cell within 25 km of Gujangbagh, so the numbers on this page are model estimates. Models capture regional pollution well but can miss very local sources such as a busy road or a nearby fire.
Wildfire smoke
PM2.5 is forecast to reach 101 µg/m³ in the next 24 hours while NASA satellites detected 1 fire hotspot within 300 km in the last day (nearest about 40 km away). Smoke is a likely contributor: keep windows closed, run an air purifier or HVAC filter, and check the fire map before heading out.
Advice for sensitive groups
At 174, children, older adults, pregnant people and anyone with asthma, COPD or heart disease should limit time outdoors, especially strenuous activity. A well-fitted N95/FFP2 mask cuts particle exposure; it does not filter ozone.
What the US AQI numbers mean
| US AQI | Category | What it means |
|---|---|---|
| 0-50 | Good | Air quality is satisfactory and poses little or no risk; a good time for outdoor activity. |
| 51-100 | Moderate | Acceptable for most people. Unusually sensitive people should consider shortening long or heavy exertion outdoors. |
| 101-150 | Unhealthy for Sensitive Groups | People with heart or lung disease, older adults, children and teens should cut back on prolonged or heavy exertion outdoors. |
| 151-200 | Unhealthy | Everyone should reduce prolonged or heavy exertion outdoors; sensitive groups should avoid it and keep windows closed. |
| 201-300 | Very Unhealthy | Health alert: everyone should avoid prolonged or heavy exertion outdoors, and sensitive groups should stay indoors. |
